The Einsatzstab Reichsleiter Rosenberg (ERR), the “Special Task Force” headed by Adolf Hitler’s leading ideologue Alfred Rosenberg, was one of the main Nazi agencies engaged in looting cultural valuables in Nazi-occupied countries during the Second World War. The detail with which the ERR documented the art, archives, books, and other Judaica it plundered has proved essential for the recovery of cultural valuables after the war and their return to victims or heirs.

Presented here are a series of interlocking, major complex projects that provide information on the location of the records of the ERR, access to images of most of those records, and research on specific items that were plundered.
